FOLDING BOX.

Application filed July as, 191 Serial li e. 8 2,Sf.9.

To all whom it may concern:

Be it known that I, LUCIAN RosnNwaLD, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented a certain new and useful Improvement in Folding Boxes, ofwhich the following is a specification.

My invention relates to improvements in folding boxes.

It is particularly adapted for use in berry or fruit boxes.

The object of my invention is to provide a novel folding box which ischeap to construct, easily extended or collapsed, and which has greatrelative strength and durability.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawing which illustrates the preferred embodimentof my in vention, Figure 1 is a perspective view of my improved box,shown extended and partly broken away. Fig. 2 is an enlarged verticalcross sectional view of the box, the U shaped brace being omitted. Fig.3 is a reduced perspective view of the U shaped brace. Fi l: is an edgeview of the box collapsed. Fig. 5 is a plan view of the box collapsed.Fig. 6 is a plan view of the strip, which forms the sides of the box,stretched out. Fig. '7 is a plan view of the Y strip, which forms thebottom, stretched out.

Fig. 8 is a top View of the box, reduced, the removable bottom memberbeing omitted. Fig. 9 is an enlarged vertical sectional view of the box,a lower part thereof, only, being shown, and the removable bottom memberand the U shaped brace being shown in position.

Similar reference characters designate similar parts in the differentviews.

1 designates a rectangular strip which forms the sides of the box, theterm sides including the ends of the box. The strip 1 may be of anysuitable material, such as sheet wood or card board. -t is provided witha plurality of parallel flexible joints 2, which may be formed bycreasing or scoring the strip. The strip 1 is bent at the creases, whichare at right angles with the longitudinal edges of the strip, to formthe shape of box desired, a rectangular box being shown, and the ends ofthe strip are secured together, as shown in Figs. 1,2 and S.

A second rectangular strip, having approximately the width of the lengthof the box inside, is provided with a middle reotangular portion 3,which forms the bottom of thcbox, and which at opposite edges is mentwith two vertical flexible joints 7 provided respectively in the twoopposite sides 1 which are adjacent to the longitudinal edges of thestrip forming the bottom. This disposition of the flexible j oints 6 and7 permits the box to be collapsed to the flat form shown in F at and 5.If desired, in collapsing the bottom portion 3 may be bent inwardlyinstead of outwardly along the joint 6. 1

The flaps 5 double two sides of the box, thereby lending strength to thestructure and melting the box more durable and less liable tobedistorted in use. Preferably, the bottom portion is disposed above thelower edges or" the box, thereby leaving a space for berries or fruit,when the boxes are piled one on top of the other. I

For holdingthe sides and bottom securely extended, a removable bottommember 8 of substantially the inner dimensions of the box, or a littleless, maybe mounted between the sides 1, is adaptedto rest upon theupper side of the bottom portion 3. The member 8 prevents the bottonipontion bending upwardly along the joint 6. if desired, additional meansfor holdingthe box extended may be provided in an inverted shaped brace,the transverse portion 9 of which is disposed transversely to the joint6 and is adapted to bear against the under side of the bottom portion 8,so

as to support the same and to prevent its bending downwardly along saidbrace is provided at its ends with downwardly extending arms 10, eachpreferably U shaped so as to be adapted to clamp the adjacent side 1 ofthe box, Fig. 9. After the box has been extended to the position shownin Fig. 2, the bottom member 8, when used, is placed therein upon thebottom portion 3. The brace is thenapplied, opposite sides of the boxbeing slipped into thell the joint 6. The

shaped arms 10, after which said arms may be :tastenedto the sides byindenting them w'vith a suitable punch, notshown therebyformingindentations l1 in the arms andin the sidesof thebox, theindentations inter= arms 10 are sprung apart suiliciently to permittheirremoval from the sides engaged thereby. The brace may then be removed,

after which the box may be collapsed by pressing the joint 6 downwardlyor upwardly and pressing the sides of the box toward each other.

r I do not limit my invention to the structure shown and described, asmodifications, within the scope o1 the appended claims,

maybe made without departing from the spirit of my invention.

ll-laying thus described my invention, what I claim and desire to secureby Letters Pat-j I cut, is 2-- l. A folding box comprising a pluralityof sides -flexibly connected at the corners of the box, two oppositesides having each a vertical flexible joint intermediate of adjecentcorners two flaps secured respectively at their upper ends to oppositesides of the box adjacentito the upper edges thereof, and havingabottomportion provided with a transverse flexible joint in alinementwith I said vertical'joints, the bottom portion being disposed above thelower edges of the box and flexibly connected at opposite edges with thelower ends respectively of said flaps, and an inverted U shaped memberhaving its transverse portion disposed below said bottom portion, eachof the arms or" the U shaped member being U shaped and adapted to clampthe adjacent side of the box. 1

2. A folding box comprising a plurality of sides flexibly connected atthe corners of Copies of this patent may be obtained for the box, twoopposite sides having each a flexible vertical joint intermediate ofadjacent corners of the'box, and having a bottom portion flexiblyconnected at opposite edges with opposite sides of the box and disposedabove the lower edges of the box and provided with a flexible transversejoint in alinement with said vertical joints, and a U shaped memberhaving its transverse portion disposed transversely to said transverseand provided with a fiexibletransverse joint in alinement with saidvertical joints, and

an inverted U shaped member having its transverse portion disposedtransversely to said transverse joint and adapted to support said bottomportion, the arms of said member each being U'shaped and said arms beingadapted to respectively clamp opposite sides of the box,

4-. A folding box having a plurality of sides flexibly connected at thecorners, two opposite sides having each a central vertical flexiblejoint, the box having a bottom flexibly connected with the other twosides of the box and having a flexible joint in alinement with saidvertical joints, and an inverted ll-shaped brace disposed below andadapted to support said bottom, the arms of said brace being U-shapedand adapted to clamp two opposite sides of the box. e

In testimony whereof I have signed my name to this specification inpresence oftwo subscribing witnesses.
